Delta is expected to become the first North American carrier to take Airbus’ updated “neo” variant of the A330 widebody, with the first delivery expected to come this year.

“There’s not an immediate impact, but it certainly could have an impact downstream on us,” West said.

As for the A220, Bastian said Delta does not anticipate having to cancel any flights or routes if there’s a delay. Instead, Delta can keep flying other planes on the routes where it expected to add the A220.

The narrowbody planes, formerly known as the Bombardier CSeries, seem a candidate to become a passenger favorite. Delta's A220s have large overhead bins and feature two-by-three seating in economy, meaning fewer middle seats. All of the plane's seats will be wider than the industry average.

Delta has ordered two versions of the jet, with the smaller seating 109 passengers and the larger 130. Delta expects all 90 of the A220s it has ordered to be delivered by the end of 2023.
